You are right. In circle equation we have =r² so the correct answer will be C od D. But we have to calculate the center of a circle.

Complete the square:

And we have:

So the answer is C (the same left side of equation).
Answer:
The answer is a unique triangle.
Step-by-step explanation:
9+7=16, 16 is less than 18.
If two sides are added up and equal or are less than the third side, they are a unique triangle.
11%=11/100
11/100=22/x
we have to solve for x now
11x=2200 divide by 11 both side
x=200
that the answer
Step-by-step explanation:
Equation of given line is:

Thus, the slope of required line is 2.
